It -is found that the Windows in the same building Will vary slightly in size and Ythat there is a considerable discrepancyfin the sizes of Windows in different buildings which are supposed to have the same size of frames.

This :results in the necessity of building. `frames especially for each Window or to use a screen having va spring-pressed adjustment .which has'never proved 4to be satisfactory. Another' difficulty that is encountered 1n 1nparallelbut are, outrf squareWith thersill. l

In Figures 5 and 6, I have 'shown a dierent method `of adjusting a screen to )peningsl which are irregular Ior which vary slightly 1n size. In these views, I have shown the frame composed entirely of sheet metal Vbut it will be understood that adjustable 'compensating pieces may as readilybe applied to' the metal covered frame 'shown in Figure 1. "In theV form of frame construction shown, the body part of the frame is angular in crosssection to provide a. ledge 26 anda back 27 above which is disposed a Z-shaped clamping part 28 terminating in a double-thick lip 29 Awhich overlaps ledge26 and vscreen clotli 12. 'The outer thickness of the metal is then bent parallel to the plane of the frame to form a guide 30 slightly spaced from clamping part 28 to vform a guideway 31.

A compensating piece is slidablymount-` l ed in a guideway 31 and provided with a plu- I rality of .bolts 33 which extendy through slots 34 formed in guide 30 in order to allow com# pensating piece 32 to be adjusted transversely while held against longitudinal movement.V Asthe strain .on bolts 33 is very slight, they are provided with very thin nuts "35 which ,i side compensating may abut the outer surface of guide V30, `as

f shownV in Figure 7, or be disposed in recesses 36, as shown in Figures 5 and 6.

A screen madein this manner may beprovided withcompensating pieces on each side only, in which case the ends of the compensating pieces will be flushV with' the bottom of the screen frame, Y compensating pieces von the top or bottom, as shown in Figure 5; LIn this case, the bottom compensating piece isma'de to overlap'tlie pieces and an auxiliary compensating piece 37 .mounted onV the lower end of each side compensating lpiece 32 by having a slot :38 through which the lowermost bolt 33 extendsso that auxiliary piece .37 may be raised or lowered toV allow for the distance that the bottom compensating ypiece extends' beyond its guideway.

.. The construction shown in Figure 7 is very similar to thatishown in Figure 6 with the exx; ception that the body partv of the-trame is provided with double-thick ledge 26a, douvis extended beyond thebody part toform'a compensating piece 18 which v'functions in exactlythe'jsame manner as compensating piece 18 shown in Figure 2.

In forming the trame members, the body or Vit'may be provided with partis bentat 16a so that the clamping part extends at approximately r" to the plane oi7 the screen; screenlcloth l2-'is then placed in4 From-the foregoing, itis apparent that a greatv variety of screenfframes 'may be Vproduced whichl will embody the' essential features of my invention";'the` forms illustrated are" merely repre'sent'ative of thefpossibilities of 'combining a fixed traine member with a fixed or adjustable compensating piece to `enable Vthe screen to beexactly tted thanV vopening whose sidesare not parallel or-whose y ends are .notat right anglesto its'sides.
